Toyota's new generation plug-in hybrid Prius will be shown for the first time next week at the Frankfurt Motor Show, and now we've got some new images and details. As expected, the PHEV Prius will be equipped with a lithium-ion battery pack. The hybrid synergy drive system has been upgraded for the PHEV allowing the Prius to operate in EV mode at speeds up to 62 mph for up to 12.5 miles. The car can apparently accelerate all the way from a standing start in EV mode, although it's not clear how quick it will be. While doing this, the Prius apparently emits about 60 g/km of carbon dioxide. The range and emissions estimates are all based on the EU driving cycle, so the numbers should be a bit more realistic than the absurd Japanese 10/15 cycle.

The battery capacity has not been announced yet, but it can be fully charged from a 230 V supply in just over 1.5 hours. Toyota plans to build 500 of these lithium-batteried Priuses starting late this year for leasing to fleets in Japan, the United States and Europe. Retail customers won't get their turn until about 2012.
